The role of R&D and economic policy uncertainty in Sri Lanka’s economic growth

In this paper, we assess the role of investment in research and development (R&D) and economic policy uncertainty (EPU) in Sri Lanka’s economic growth experience. We do this by first determining which endogenous growth theories best explain the evolution of total factor productivity (TFP) in the country. Using historical time series data (1980–2018), we find that semi-endogenous growth theories best explain the evolution of TFP in Sri Lanka. This evidence suggests that R&D is critical to the country’s TFP expansion. We find that, through R&D, EPU has a crucial detrimental impact on TFP growth, although it is short-lived. Our findings are robust and have important implications for R&D investment and for moderating EPU.

Media reporting on public procurement: an analysis of UK press coverage, 1985–2018

Purpose The media is an important actor in public procurement, but research on its role is limited. This paper aims to investigate how the media has engaged with public procurement, using UK newspapers as a case example. Design/methodology/approach The method consisted of searching Nexis database for news articles on public procurement; automatic extraction of article attributes such as length, section, authorship; and manually coding each article for its theme and industry context. This produced quantitative indicators about the extent and focus of press coverage on public procurement. Findings Press coverage of public procurement increased between 1985 and 2018. The focus of coverage has been on governance failure and socio-economic policy. Governance failure, which includes corruption, cronyism and supplier malpractice, is associated with construction, outsourcing and professional services sectors. Socio-economic policy, which includes supporting small suppliers and favouring domestic industry, is associated with manufacturing, defence and agriculture. Research limitations/implications The analysis included UK media only. While the trends observed on the extent and focus of public procurement news coverage likely reflect the situation in other countries, international comparative research is still required. Practical implications Government officials should be more proactive in countering the “negativity bias” in news coverage of public procurement by showcasing projects where value-for-money has been achieved, services have been successfully delivered and social value has been realised. Social implications The media accentuates the negatives of public procurement and omits positive developments. The end-result is a selective and, at times, self-serving media narrative that is likely to engender cynicism towards public procurement. Originality/value To the best of the authors’ knowledge, this is the first study on media coverage of public procurement. It highlights that while there are similarities between media and academic treatment of public procurement, particularly in relation to its socio-economic side, the media emphasises governance failings and negative developments to a greater extent.

Does Economic Policy Uncertainty Affect Exchange Rate in China and Japan? Evidence from Threshold Cointegration with Asymmetric Adjustment

In this article, we estimate the links between nominal exchange rates (JPY/USD and CNY/USD) and economic policy uncertainty (EPU) in China and Japan by employing monthly data during the period span from January 1997 to September 2020. The threshold cointegration approach focus in TAR, M-TAR, C-TAR and C-MTAR is used. Results indicate the evidence of asymmetric effect in the adjustment process to equilibrium and the M-TAR is the best model to detect threshold effect for the (CNY/USD-CNYEPU) pair and the C-TAR is the best model to detect threshold effect for the (JPY/USD-JPYEPU) pair.

Evidence of Economic Policy Uncertainty and COVID-19 Pandemic on Global Stock Returns

This paper examines the impact of changes in economic policy uncertainty (EPU) and COVID-19 shock on stock returns. Tests of 16 global stock market indices, using monthly data from January 1990 to August 2021, suggest a negative relation between the stock return and a country’s EPU. Evidence suggests that a rise in the U.S. EPU causes not only a decline in a country’s stock return, but also a negative spillover effect on the global market; however, we cannot find a comparable negative effect from global EPU to U.S. stocks. Evidence suggests that the COVID-19 pandemic has a negative impact that significantly affects stock return worldwide. This study also finds an indirect COVID-19 impact that runs through a change in domestic EPU and, in turn, affects stock return. Evidence shows significant COVID-19 effects that change relative stock returns between the U.S. and global markets, creating a decoupling phenomenon.
